To all to 710m it may concern:

Be it known that I, ALBERT G. Sonnnnn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful, 1m provement in Heating Devices, of which the following is a specification.

My present invention relates to heating systems, and more particularly to the type ments that are expensive in manufacture and known as the monopipe hot air system,

that is, a furnace or heater from which a single large hot-air discharge pipe leads up.- wardly to a single register structure for the distribution of the hot-air and which generally receives thecoolair returnedito the furnace or heater for reheating through an other portion of the same register structure.

When a register structure is to be placed in a position such as against a wall or upon both sides of a partition Wall, as disclosed in my prior Letters Patents of. February 3, 1920,' Numbers 1,329,802 and 1,329,804., the vertical plane of the back" of the register is, of course, parallel with the plane of the wall, and as this cannot be changed or moved difficulty may be encountered in makingthe installation owing to the'fact that the front of the furnace or heater had tolbe parallel with the plane of the Wall'so that slight de-' viations therefrom meant considerable un necessary labor and time in erecting the fur nace or heater unless great care Wasused. Also it may be, and often: is desirable to face the furnace with the coal and ash doors in front of bins or receptacles so as to more conveniently handle the coal and ashes, which of course could not be done where there is no adjustability or relative movement provided for between the register and the furnace structure.

' In myv present structure-I have so co 'related the furnace, the air supply. and discharge pipes, and the register structure that much time and labor are saved in the erection of the furnace and the installation of the pipes and register structure,gand to accomplish this co-relation of the elements, I have disposed the register structure above the furnace structure with their axes co-inciding or in longitudinal. alinement' I am enabled by this construction to assemble the furnace and pipes and thenswivelor rotate the register until its vertical plane; is parallel with the vertical plane of the wall against whJchthe register is placed. Also, I amen- 'abled' to dispense with considerable pipe-be tween the floor and the top of thefurnace or heater, and, toa great extent, make use of stock or commercial pipes, boots and boxes in the erection of the entire structure, thereby dispensing with specially formed eleto replace; Other objects and advantages will be obvious to others skilled in the art after an understanding of my inventionis had, and I-prefer to accomplish these divers objects in substantially. the manner hereinafter described and as illustrated in the ac:

companying drawings that form a part of this specification, in which;

F g. 1 is a vertical front elevation of? my invention, portions of the walls whereof are broken away and in section to more clearly disclose the structure. 7

In carrying out my invention any suitable register structures maybe employed: for the d scharge of'the warm air and returnof the cool air, I'prefer, however, tomake use of register Structures, similar to those disclosed in my prior Letters Patent 0f the United States, and my pendin application Serial No. 874,892 for Letters Patent of the United States, filed April 19, 1920; which matured May 30, 19-22, in Letters Patent No. 1,417,772,

(of which the present application is a divi sion), wherein reticulated w'alls extend above the level-of the floor-and partially or whollv surround a two--coinpartment chamber fdr hot and cold air, although it will be understood that ordinary floor registers or floor grilles may be used as well:

Brieflyv stated, the registerhody shown in my present application comprises two metal plates 10 forniin the double rear wall that 'the fioo rj Lateratflangesl? on the endsoi' V the grilles are connected by bolts 18 to anglepieces 19 on the side plates 11; V .7

Two vertically disposer converging walls "24 extend forwardly towards each other from the oppositecorners' formed by side 7. plates 11 and rear walls 10 anonieet at 'a point slightly to the rear of thefront portions of the'l'ower grille; The upper edges of these'walls' terminate at approximately one-half the height ofthe register, while their lower portionsiextend a suitabledis tance below thestrap or ring 14, the pur pose whereoi" will shortlybe explained." It might be here stated, however, that said walls 2d, together with rear wall 10, provide the triangular shaped upper portion of the hot-air passageway, and area continuation of the hot-air condnit leading r v v 1 1 from the furnace structure below the floor,

and said walls 2d also divide the interior of thelowerportion of the register into two substantially equal 1 portions, .the outer whereof is for cool air Each wall2l has a triangular shaped recess 25 1) ex:

tending downwardlyrfrom its npp-er edge in order to receive the edgosoi ti'in deflectors 26 of-pyra'midal shape and having their .apices inverted, as-seen in Fig. 1-, so that they flare outwardly towards and meetthe front and side walls or'grilles' of the regis ter structure. From-1 the foregoing'it will be seen the register is open upon its front 'andboth' side's,",and there is no interference or retarding of the two currents of air becauseof the fact that the heated air is discharged throughthe upper grille in an upward an-dcoutward, direction, "while the cool, ,air is moving towards the register in substantially. a horizontal direction, and is taken in through the lower grille, as indicated by the arrows in Fig; 5.

' The upper edge of the furnace shell or.

casing 13 carries a T-section annulus or ring 28 from which a frustrum conical shaped.

bonnet 29extends inwardly at about a degree angle, anda cylindrical-pipe 30 is secured to'the upper edge of the bonnet so that'its axis is in longitudinal alinenient with theiaxis of the furnace casing. Telescopingwithpipe 30 is a similar pipe 31', as seen in Figs. 1 and 3 to permit of adjustmeht for the varying'distances between vbonnet 29 and the floor supportingthe reginto the lower portion of shell 13.

with the lower portion of converging walls 24 and rear wall 10, and in order to do this the lower edge 32 of the adapter is made round or cylindrical to lit pipe 31; its rear -po1tion'32 is fan-shaped or flared towards its top to meet the straight edge of wall 10 of the register; and the remaining upper portion is parallel with Walls 2%, or, in other words, the upper edge of the adapter 32 is triangular, while its lower edge is round, the sides merging into each other to provide this peculiar shape. A pocket or seat 3;) is formed at the upper edge of the adapter by bending the metal down and then up to receive and have the lower edges of one plate oiwalls 10 and wall 24 secured thereto, thus providing a hot or warm air passageway from the hot-air chamber within the shell to the hot-air passageway of the register.

Resting upon the flange or annulus 28 is a cylindrical wall 34 the upper cdgewhereof terminates slightly above the horizontal plane of the top of bonnet 29 and is ])ro vided with a plurality of openings 35 lo which cold-air return pipes 12 are connected and lead to and discharge the return air A T- section annulus or ring 36 is mounted upon the upper edge of wall 34, while an outer bonnet formed of a converging wall 37, of somewhat 'frustum conical shape, has its lower cylindrical flange 38 resting uponthc lateral member of annulus 36, as illustrated in detail in Fig. 4 of: the drawings. Another T-shap'e annulus 39 is fitted to the upfper edge of'outcrbonnet 37 and is secured thereto bybands in. substantially in the manner shown in Fig. 4,. 1 have, however, shaped annulus 39 to conform approximately to the contour of the lower edge of the register structure,that is it is substantially rectangular,-and the sides of the walls 37 of the bonnet merge into each other to conform therewith at their upper edge while retaining their circular or cylindrical shape at the lower edge.

I In order to make connection between this outer bonnet or conical wall 37 and the lower portion of the register front, side and rear walls I secure a sheet metal apron 41 to the inside face of the vertical flange of lower strap 14 so that said apron depends therefrom and passes through the opening in the floor. A skirting 42 is now out from sheet metal of a width corresponding with the distance between strap 14 and annulus 39. This skirting is made preferably in two pieces the edges overlapping and has 0 positely arranged angle brackets 43 thatmay be drawn towards each other by clamping received by the register through the lower grille 16 down between the adapter and skirting, then over the bonnet 29 between the latter and cylindrical wall 34, and discharges the same through apertures to the return pipes 12 leading down into the furnace shell 13.

In setting up or assembling the structure, the register is placed on the floor-after the proper'opening has been made therein, and in building up the furnace shell and superposed structure, walls 34 and 37 may be rotated to aline annulus 39 with apron 41 without having to move the furnace, and the register may be rotated to aline it with the wall of the building against which it is to be fitted at the same time rotating adapter 32 with its telescoping wall 31 on the fixed wall 30 of the hot-air passage way; This will permit of setting the furnace so that its feed and ash doors are ,in any desired position, as, f'orexample, conveniently in front of a bin or the like without regard to the vertical plane of the wall against which the back of the register is to be placed as the structure above the furnace shell may afterwards be rotated to aline the register with the wall. When properly adjusted, skirting 42 is cut the proper height and secured in place, thus saving considerable time and labor in assembling the entire structure.

I am aware that divers changes or alter ations may be made without departing from the principles herein described, but I desire it understood that all such modifications are contemplated within the scope of the appended claims. In this connection, I wish to state the drawings and description here in given are merely typical andI do not limit myself to the precise structure shown and described;

What I claim is 1. The combination with a register structure and a conduit leading into the same, of a furnace casing of cylindrical shape, a bonnet mounted upon the top thereof and having a central opening, telescoping pipes connected respectively to said bonnet around said opening and to said conduit, a cylindrical wall extended above said casing, a second bonnet mounted upon said cylindrical wall and having rotative movement with respect thereto, and a wall substantially conforming to the contour of said 7 register and second bonnet clamped to'the adjacent edges thereof.

2. A device ofthe kind described comprising the exterior casing of a furnace, a structure above said' casing having inner and outer conduits, a bonnet mounted on the top of said casing, means revolvably connecting said bonnet to said inner conduit, and other means revolvably connecting the top at the furnace casing with the outer conuit.

3. A device of the kind described comrising a furnace casing, a bonnet mounted thereon, a conduit wall connected to the upperportion of said bonnet and establishing communication with the interior of the casing, a short cylindrical wall mounted upon said casing and capable of rotatable adjustment thereon, a second bonnet mounted on said cylindrical wall, and a conduit wall connected to the upper portion of said second bonnet and spaced from said first conduit wall, whereby said furnace casing may be rotated bodily with respect to the structure above the same.

Signed at Chicago, county of Cook, and State of Illinois, this 7th day of April, 1922.
